Astros signed INF Reid Brignac to a minor league contract with an invitation to spring training.

The 30-year-old spent the 2016 season in the Braves' organization, slashing .264/.361/.394 with eight homers and 42 RBI in 102 games at Triple-A Gwinnett. He'll add organizational depth to the Astros but is a long shot to crack the Opening Day roster in a reserve role.

The 26-year-old spent the first seven seasons of his professional career in the Brewers' organization. He split his time between Double-A Biloxi and Triple-A Colorado Springs in 2016, compiling a 4.30 ERA, 1.23 WHIP and 79/28 K/BB ratio over 98 1/3 frames.

Diamondbacks signed RHP Asher Wojciechowski to a minor league contract.

The 27-year-old hurler posted a 4.94 ERA, 1.60 WHIP and 63/38 K/BB ratio over 85 2/3 minor league innings between the Astros and Marlins in 2016. He'll add organizational rotation depth for the D'Backs.

The 33-year-old has appeared in only 21 big league games since the 2011 season, but he refuses to give up the dream. He sat out the 2016 season entirely after slashing a terrific .310/.380/.515 with 20 homers and 89 RBI in 127 games at Triple-A Nashville in 2015.

The 25-year-old was a first round selection of the Red Sox in the 2009 draft. He appeared in 13 games for the Royals in 2016, slashing .317/.364/.341 with five RBI in 44 plate appearances. He'll likely be given an opportunity to compete for a reserve outfield spot on the club's Opening Day roster.
